WINDOW REGULATOR FOR VEHICLES.

Application filed March 4, 1927.

This'ii vention relates to a new and use ful device in the nature of a window regulator formotor vehicles, particularly adapted'for the purpose of opening andclosing windows in motor vehicles of the closed body type.

An object of the invent-ion is to provide a window regulator easily and readily removable in event of repairs or replacement.

A further object of the invention to provide a window regulator for motor vchi'cles, of novel construction and arrangement of parts, hereinafter, more fully described, claimed, and illustrated in the accompanying drawing.

Fig. 1 is a side elevational view of a motor vehicle of the closed body type embodying window regulators constructed in accordance with the invention.

Fig. 2 is a top plan view of my improved window regulator.

Fig. 3 is a front elevational view thereof, partly fragmentary so as. to more clearly show the interior construction thereof.

Fig. 4 is an enlarged transverse sectional view taken on the line 44 of Fig. 5.

Fig. 5 is a front elevational view of my improved window regulator, illustrating same in a partly removed position.

Fig. 6 is a vertical longitudinal sectional view taken on the line 66 of Fig.

Fig. 7 is a fragmentary front elevational view of a modified form of my invention.

Fig. 8 is a fragmentary sectional view of a detail of my invention.

As here embodied I have provided a cross member 10, having attached thereto, and extended downwardly therefrom vertical members 11 and 12. The guide members 13 and 14, are attached to the vertical members 11 and 12, respectively, and are extended. inwardly therefrom.

The above described construction being such as will provide a sup )oi.'ting means or frame adapted to slidably receive my improved window regulator. It being understood that the above described supporting means may be constructed integral with the motor vehicle, the cross member 10, comprising the window sill.

As here embodied my improved window regulator comprises a frame work, consisting of upright members 15 and 16, and having attached thereto a lower cross member 17. The plate member 18 is attached there- .to, at the front thereof. The above described frame work is slidably mounted in the here- Serial No. 172, 584.

tofore described supporting means. The engaging members 19 and 20,.are attached to the upper extremities of the upright members 15 and 16, and are extended there from, so as to engage in openings 21 and or grooves formed in the above mentioned cross member 10. The engaging members 19 and 20, are provided with apertures 23 and 24, adapted to receive screws, bolts or the like, as a means of attaching my improved window regulator in place in the above described supporting means. I

The rear plate member 25. is attached to the upright member 15, and to the intermediate upright member 26. The cylindri- "al member 27 ,is rotatively mounted in the plate members 18 and 25, and is provided with an opening 28, preferably of square cross-section. The gear 29, is attached to the cylindrical member 27, and meshes with a gear 30 attached to the drum 31. The drum 31 is rotatively mounted in the plate members 18 and '25. The helical spring 32 is wound or positioned in the drum 31 and is attached at its inner extremity, as at 33, by a clip or the like to the rear plate member25. The outer extremity of the spring 32 is attached to the inner portion of the drum 31.

The flexible member 34, is attached to the drum 31, and is extended over the periphery thereof, and is attached at its extended extremity to the engaging member 35, provided with an extended portion 36. The flexible member 37, is attached to the engaging member 35, and extended downwardly therefrom, over the pulley 38. rotatively mounted in the bracket 39. The expansion spring 40. is attached to the bracket and to the clip 41. attached to the above mentioned lower cross member 1.7. T be flexible member 37. is extended upwardly fromv the pulley 3S, and is extended overthe periphery of the drum 31, and is attached thereto.

The above described construction being such as will. permit the cylindrical member 27 when rotated or turned by a handle, not shown in the accompanying drawing, which is provided with an extended element, adapted to slidably engage in the opening 28, to raise and lower the engaging member It being understood that the extended ele- 'ment 36 of the said engaging member is adapted to engage in an elongatedslot 44, provided in the plate member 45, secured to the lower frame of a window 46 of a motor vehicle of the closed car t Je so as to ooen and close the said window. It being understood that the engaging member 35, when the I I have shown the extended element 36 of the engaging member 85, provided with an axial aperture adapted to receive the threaded member 42, provided with an enlarged head 43. The above described construction being such as will permit the threaded member to be extended so as to fully engage under the above mentioned window or window frame.

Having thus described my invention what I claim as new and desire to protect by Letters Patent oi? the United States is as follows:

A window regulator of the class described comprising aframe, inner and outer side plates mounted on said frame, said i 4 ner side plate being provided with a longitudinal slot having an enlarged upper end a drum rotatively mounted in said frame between the side plates thereof, a pulley attached to the bottom of said frame, a flexible member attached to said drum adapted to be wound thereon and disposed around said pulley, an engaging member slidably mounted in said frame, attached at one end to said flexible member and disposed at its other end through said slot, and a plate having a transverse slot therein slidably mounted on said attaching member. and comprising a window supporting rack, said engaging member and said plate being adapted to be raised and lowered by rotation of said drum for raising and lowering a Window mounted on said rack and said engaging member being adapted to be moved relative to said.

plate for positioning the former in the. enlarged portion of said slot When the window is in its uppermost position to prevent aecidental. lowering thereof.

In testimony whereof I have afiixed my signature.
